CmGRX Gene Family in Chinese Chestnut: Identification and Stress Response

32 Glutaredoxin (GRX) genes identified across the Castanea mollissima genome provide a foundation for studying plant stress adaptation. The data includes phylogenetic classification into CPYC, CGFS, and CC subfamilies and reveals expression patterns under high/low temperature, salt-alkaline, and shading stresses. This dataset, authored by Xili Liu and last updated in May 2026, offers gene resources for developing resilient chestnut varieties for ecological restoration.

Use Cases

• Phylogenetic analysis of the GRX gene family based on the identified 32 CmGRX genes.
• Identification of stress-responsive cis-acting elements and transcription factors (ERF, MYB, NAC) based on promoter analysis.
• Comparative expression profiling under different abiotic stresses (temperature, salt-alkaline, shading) based on transcriptomic data.
• Investigation of gene family expansion mechanisms based on the inference of dispersed duplication events.

Strengths

• Contains a specific count of 32 identified CmGRX genes.
• Includes validation of RNA-seq data through RT-qPCR analysis as mentioned in the description.
• Provides evolutionary context with genes categorized into three distinct subfamilies (CPYC, CGFS, CC).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (378.5 KB), indicating limited scope beyond the core gene list and associated analyses.
